Training Course #1
ConditionBased Aircraft Post Inspection Reliability Analysis (4HR)


Instructor: Dr. Mohammad Khalessi, PredictionProbe Inc

Course Time: Monday, November 26, 2018 / 8:00 AM - 12:00 PM (View on Agenda)

Course Description:
Aircraft structural risk and reliability analysis is a vital and growing element of the United States Air Force (USAF) Aircraft Structural Integrity Program. As the age of the USAF inventory increases, the cumulative effect of structural repairs is a growing threat to aircraft structural integrity. Using APIRA™ Software, the proposed training will demonstrate how to account for the diversity and complexity of structural repairs and accurately predict the structural reliability of various repair scenarios and their cumulative effect. The APIRA™ Software has been developed under the USAF Contract Number FA8650-15-C-2565 for Condition-Based Aircraft Post Inspection Reliability Analysis (APIRA™). This software will: a) allow the user to define and construct any implicit or explicit models that can describe complex repairs, post-inspection conditions, various failure criteria, and complex input random variables including conditional and user-defined random variables; b) provide the user with the capability to define and store, in a library, many repair models to be used for various repair scenarios; c) enable the user access to, and use of more advanced probabilistic, statistical, and numerical integration methods available in SPISE®, UNIPASS®, or any other third party tools to calculate the single flight probability of failure (SFPOF), cumulative probability of failure (POF), crack size distribution (CSD), etc.; d) allow the user to perform Bayesian updating of the variables and analysis when inspection and maintenance data becomes available using the SPISE® Bayesian Module; and e) much more.

This course prepares attendees to systematically quantify and analyze the risks that are inherent in decision-making related to availability, safety, costs, and fleet management, so that decisions are made more confidently, efficiently, consistently and accurately.

This training provides attendees with invaluable information and resources to:
• Assess how big of a problem there is in the fleet, in terms of SFPOF, when a fatigue crack has been found in a location that has no previous damage tolerance analysis and no inspection requirements.
• Determine after a TCTO has been issued: a) when it should take effect (aircraft flight hours); b) the length of time that the field has to comply with it; and c) the best available Non-Destructive Inspection (NDI) method.
• Determine if inspection results (e.g., number and size of cracks found) are as expected or if not: a) update the EIFS distributions based on the findings using the Bayesian Updating Rule; b) revise TCTO compliance period and/or aircraft effectivity (more cracks found than expected); c) improve NDI execution improvements (less cracks found than expected), and d) adjust other analysis inputs (either more or less cracks found).
• Schedule aircraft for depot maintenance based upon their level of risk.
• Determine safety, availability, and cost impacts for service life extension and repair/replacement options.




Training Course #2
AFGROW Version 53 Training (4HR)


Instructor: Mr. Jim Harter & Mr. Alex Litvinov, AFGROW

Course Time: Monday, November 26, 2018 / 1:00 PM - 5:00 PM (View on Agenda)

Course Description:
This training class will review the basic Linear Elastic Fracture Mechanics principles used in the crack growth life prediction program, AFGROW. The class will also provide an overview of the use of the software including practical life prediction examples and the use of automation capabilities to perform repetitive and/or complex life prediction tasks.




Training Course #3
Modeling Fastened Connections: Hierarchic Approaches
Discussion and Demo (2HR)


Instructor: Mr. Eric Buettmann, ESRD, Inc.

Course Time: Monday, November 26, 2018 / 6:30 PM - 8:30 PM (View on Agenda)

Course Description:
Reliable, high-fidelity analytical procedures for assessing fastened connections are critical for reducing unnecessary conservatism in design, reducing excess weight, increasing affordability and structural integrity, and decreasing the frequency of periodic inspections. These benefits can only be realized using properly formulated models solved by numerical methods, when the model definition and its numerical approximation are treated separately (a technical requirement of Simulation Governance). A hierarchic modeling strategy will be discussed to determine the simplest model from a family of models of increasing complexity that will provide reliable results for the intended use of the model, such that verifiable, relevant data from the region of interest can be extracted.

This short training course will discuss a hierarchic approach to modeling fastened joints using Finite element Analysis (FEA) with specific examples and case studies using professional FEA software. Model conceptualization, including all simplifying assumptions based on both the available information and the data of interest will be covered as well. Different models from the hierarchy will be demonstrated and compared to showcase how selecting the best model can save time and money, without compromising structural integrity or accuracy. The course will emphasize key post-processing capabilities that enhance the quality and reliability of contact analysis results.

• Modeling of fastened connections – a hierarchic approach using FEA Software – including shear connections ignoring secondary bending, full multi-body contact (load transfer between all parts), partial contact (load transfer between notable parts only), and the use of compression-only distributed springs for single part analysis approaches.
• Pros, cons and applicability of each hierarchic modeling approach will be analyzed.
• Case Study: 3D bolted Lug Comparison – (1) Multi-body contact, (2) partial contact simplification & (3) compression-only distributed springs.
• Live StressCheck Demo: Students will learn the process of checking reactions in contact regions/holes, as well as how to perform live-dynamic processing of detailed stresses in multi-part assemblies.
• Q&A

 

ASIP has always been an excellent conference over the past 30 years for the opportunities I have had to participate during that time.

I attend a lot of conferences, and this one is the best! The organization is thoroughly professional, yet still friendly. I love the technological features, such as the conference app.
